Twin Photobeam Multi-Frequency Detectors with Laser Beam AlignmentCE logo
E-964-D390Q - 390ft (120m) outdoors, 790ft (240m) indoors

ENFORCER Long Range Photobeam Detectors are easy-to-install with laser beam alignment and provide extended range. Designed to provide reliable perimeter security both indoors and outdoors. With the new E-964-D390Q, four selectable beam frequencies reduce interference between multiple units for enhanced perimeter protection.

  • Built-in laser beam alignment system speeds accurate, reliable positioning.
  • Twin infrared beams provide reliable perimeter security, minimizing false alarms from falling leaves, birds, etc.
  • Lensed optics reinforce beam strength & provide excellent immunity to false alarms due to rain, snow, mist, etc.
  • Weatherproof, sunlight-filtering case for indoor & outdoor use.
  • Anti-frost system so that beam functions even in extreme conditions.
  • Automatic input power filtering with special noise rejection circuitry.
  • NC/NO alarm output.
  • N.C. tamper circuit included.
  • Non-polarized power inputs.
  • Quick, easy installation with built-in laser beam alignment system.
  • Interruption time adjustable for nearly all situations.
